Look on the passenger app when you see a surge on the driver app. Place the pin in the surge zone on the pax app. You will notice that below the map, where you select the type of service that you want. (i.e., X, XL, Select, Black, Plus) next to the button you will see a lightening bolt. You can click on the service and it will show you the exact multiplier for the surge. Monitoring for the surge is as easy as moving the pin around and looking for the lightening bolt. Good Luck.
